To all whom it may concern: 7

Be it known that I, HENRY C. POMEROY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Riveting-Machines,ofwhich the following is a specification.

The invention relates to riveting-machines such as are used for spreadin or upsetting 1o hollow rivets, eyelets, and sim' ar devices.

One of its objects is to provide an improved post for supporting lacing-hooks when the machine is used for setting them.

Another of its objects is to provide a ma.- chine having a post designed for supporting lacing-hooks, with removable caps adapted to be easily and quickly placed upon said post, so as to be supported thereby, said caps having working faces variously fashioned, so as to receive and support devices other than lacing-hookssuch, for example, as eyelets, studs, rivets, &c.thus adapting one and the same machine, equipped with these removable caps, for use in setting any and all of 2 5 these devices. I

To these ends the invention consists in the features of novelty that are herein described with reference to the accompanying drawings, which are made a part hereof, and in which Figure 1 is a vertical section of a machine embodying my invention. are respectively a plan view, a rear elevation,

and a vertical section on the line 4 4, Fig. 2,

5 of a part herein called the post. Fig. 5

is a vertical section of one of the parts herein called a cap. Fig. 6 is a vertical section of the upper part of the frame, showing a foot-power lever substituted for the hand 40 lever.

A is the frame of the machine. At top it has a pair of ears a, located a sufficient distance apart to receive between them the cam-shaped end of the operating-lever B and the head C of the reciprocable plunger D, which fits in a vertical socket in the frame.

Figs. 2, 3, and 4:.

In rear of the vertical line of the plunger the ears have perforations a, that afford a seat for the pivotE when the hand-lever B is used, as shown in Fig. 1, and in front of said line they have perforations a, that afford a seat for the pivot when the foot-lever B is used, as shown in Fig. 6. Whichever lever is used it projects rearward from the pivot. The'cam b of the hand-lever is in front of the pivot, so that the lever moves upward and forward in advancing theplunger, and this hasthe advantage of enabling the lever to be operated by a pull instead of a push, as is customary. The cam b of the foot-lever is in rear of the pivot, so that the lever moves downward in advancing the plunger. A part of the rod which connects it with the treadle is shownat F, the frame being provided with a vertical opening through which saidrod passes. In both levers the cams are so disposed that they bear directly against the end of the plunger, and thereby avoid lateral strains upon it.

The base of the frame is provided with a cylindrical socket, in which is permanently secured a hollow post G, that portion of the post within the socket being cylindrical exteriorly. The post projects some distance above the base, and the projecting portion of it is cylindrical save that a segment is out out of it at back to provide an opening 9. At its upper end it has an integral web g, which has in its rear side, opposite the opening 9, a curved notch g. The web g forms the su port for the eyelet portion of a lacing-hoo. and the opening g and notch g allow the top portion of the hook to enter beneath the web, the notch being curved to conform to the in ner side of the shank of the hook, whereby the hook is firmly supported while being set. In the center of the web is a depression g*,

which receives the central spur d on the end of the plunger, by which the eyelet is spread. For the purpose of setting devices other than lacing-hooks, such as already described,

the machine is provided with a number of auxiliary caps II, adapted to be easily and quickly slipped onto the projecting portion of the post, one of said caps being shown in place in Fig. 1 and in enlarged vertical section in Fig. 5. This cap com rises a cylindrical portion h, which is a apted to surround the post, and an integral web h, closing the end of said cylindrical portion, the

. under side of said web being flat and adapted to seat upon the upper end of the post, while the upper side of said web is fashioned to conform to the device it is intended to be used in connection with. The one shown in the drawings is intended for use with an eyelet and has an annular groove or depression h, which surrounds a centrally located and deeper depression 7L2, adapted to receive the spur d on the end of the plunger.

By providing the machine with a permanent post constructed for use in setting lacing-hooks and with a number of these removable caps variously fashioned it may be used for setting a great variety of devices.

I am aware that it is not broadly new to provide a machine with removable tools of various styles and intended for various purposes; but, so far as I am aware, I am the first to provide a riveting-machine with a permanent post adapted for setting lacinghooks and with removable caps adapted to be placed upon and supported by said post and I variously fashioned for setting other devices.

I-Iaving described my invention, what I claim as new therein, and desire to secure by Letters Patent, is

1. A post for riveting-machines of the class described, having a cylindrical body hollow throughout, excepting at one end, and an in tegral web closing said end, excepting for a notch with which said web is provided, one side of the tubular body being provided, opposite said notch, with an opening, said notch and opening being coextensive in width, substantially as described.

2. A riveting-machine having a frame, a reciprocable plunger mounted therein, a post secured to the frame in line with the plunger and. having a hollow projecting portion provided in its side with an opening, the post also having at top a web provided with a notch opposite said opening, and a cap adapted to be slipped onto said post, said cap having a portion surrounding the post and a top portion provided with features adapted to receive and support the device to be set, substantially as described.
